The wait was finally over last Thursday for thousands of Jewish students, who woke up bright and early to receive their GCSE results.
JFS in Kenton celebrated "excellent results", with 50 per cent graded A* or A. A third of all students gained an A* or A in at least seven subjects.
More than 50 per cent of students achieved the government's EBacc measure, which allows people to compare how many pupils get a grade C or above in the core academic subjects at government-funded schools. This result was more than double the national average in 2014.
Special mention went to Jacob Arbeid and Raphael Korber-Hoffman, who each attained 12 A*s; Vitale Stone, who scored 11 A*s and one A; and Adam Lang, who won 10 A*s and two As.
"We are very proud of all our students who truly deserve the excellent grades they have achieved in this summer's exams," said JFS headteacher Jonathan Miller. "This reflects a serious amount of dedication, hard work and determination by them, their parents and their teachers. I salute them all for their achievement."
Deputy head Simon Appleman added that there had been a "pleasant atmosphere" in the school on Thursday among Year 11 students and their families. The year group hit the headlines in May after their muck-up day celebrations got "out of control" and school property was vandalised.
"I think the dust has settled since then," said Mr Appleman. "It is history, and we look forward to welcoming Year 12 back to school in September."
